IMPROVEMENT -IN CARRIAGE-BRAKES.

Be it known that I, MILES K. LEWIS, of Iowa City, in the eounty of Johnson and State of Iowa, have invented oertain new and usefu1 Improvements in Carriage-Brakes; an l1 do herebydeolare tha-t ehe same am described and represented in the following speoification and accompanying drawings.

The nature of my invention and improvements in carriage-bmkes eonsists in making the bmkeblock whioh acts on the oarriagewhee1 to turn o1 rotate 011 the brake-bar and wiud a chain whioh is fastened 130 the b1akeblock and to some part of the carriage, so as to dmw the brake-blook against Ehe whee1 as 'uhe chain is wound; also, in a oombination 0f devices by which the team, in holding back,

app1ies ehe brake to Ehe wheels.

T0 enable others skilled in the an; to make and use my improvements, I Will proceedto describe their construction zu1d operation, refening to ehe abovementioned drawings, in which the szune letzters indicate like parts in eaoh of 1;he figures.

In the drawings, A is the fore a.nd B the bind ax1e, eonneoted by the perch C, as shown in the drawings.

D D a1e hounds fastened to the axle A 130 support Ehe po1e E a-nd bar F, which bar F dotted 1ines in Fig. 2,) throug'h whioh s1ot the' pin I passes, tha1; oonnects the pole to the hounds, the s1ot II allowing the pole to be pushed back and dmwn forward by the team wnich dmws the oarriage.

J is the doubletree, fastened [0 the po1e by a holt. The upper end of this bo1tis fastened 01 ooun ected to the hounds by the chains K K, as shown in l.

The pereh C is braced by ehe hounds L L, fastened tit and to the ax1e The cross-bar M is fastened to the hounds L L '00 suppor the bmke-bar N, whioh is ma-de in the forni shown in the dmwings and arranged to rook free1y 011 the bar M in the staples P P, which fasten it 110 the bar M, zus shown in Fig. 1. The ends of the bmke-bar N a1*e rounded, and the rotatin'g brake-blocks Q Q a're fitted to tu1n freely 011 the1n. These brake-bloeks have hubs R R, and the chains S S are fastened to the axle B an'd to the brake-blooks Q Q, so that when the brake bloeks are brought against the wheels T T the friction of the rotaing wheels turns the brake-blooks and Winds the ohains S S- around the hubs of the brake-blocks and draws the brakes and bloeks ag-ainst the wheels untiL the chaius are wound so tight as to stop the brake-blocks from turning When thetendeney of the wheels is to turn the blooks farther and dmw 1:11e ohains tight-er, so that 'the harder the brake is pressed against the wheels the greater the pow r exerted by the chains to draw the b1akes a.gzinst the whee1s, thus making the brake-blocks self-aooing to a great exteub after they are applied until they are removed from the wheels.

The lever U is fastened o0 the brake shaft or bar N, and connected by the 1od V to the pole E, so that when the team holds back by ehe pole the 10d and lever applies ehe brakes 00 the wheels, and when the tea1n pulls forward it releases the brakes from the wheels, the slot H in the tongue 01' pole permitting it t-o traverse bebween the hounds f01 the purpose of working the brake. The rod V passes through a staple in the unde1 side of ehe axle A, aud the rod is joint-ed ab W, so

as to a1low oho pole to vibrace horizontally and perpendieularly without deranging tl1e rod.

I believe I have described the imfirovements in caniage brakes whioh I have invented, so as to ena.ble any person skilled in the art to make and us e bhem. I will now state whao I desire to secure by Letters Patent.

I do notclaim a 101161 or friction-wheels 120 draw a separate brake against the whee1s, as shown 2u1d deseribed in J. E. Kelleys application.

I claim Making the bmke-blooks which acta 011 'uhe oarriage wheels to turn o1 rotate on the brake-bar and wind chains which are fastened to the bmke-blooks and so son1e part of the carriage, so as t0 Wind the chains around the hub of the brake-block and draw ehe brake-blocks agains the wheels, as deseribed, am], in combinaion with the above-claimed devices, conneeting ohe brake-bmto the po1e, substantially as described, so as to operate 01' apply and release thebrake bythe team.
